The country's largest vacuum zinc infiltration production line was recently put into production in Rudong City, Jiangsu Province. It is reported that the project has invested a total of 20 million yuan, with an annual processing capacity of 10,000 tons, and the production scale ranks first in the country. It is understood that vacuum zinc infiltration is a chemical heat treatment technique in the ferrite state, so that the zinc atoms are uniformly diffused into the surface layer of the steel parts to form a strong anti-corrosion protective layer, which can effectively improve the quality of the steel products.
